The diameter is a line that stretches across the middle of a circle from end to end. The radius is one half of this line, stretching from the center of the circle to a point on the side of the circle. This means that the diameter is 2 times the length of the radius. 2 times 2 is 4, meaning that the diameter is 4 inches.

4 is the circle's diameter.

The radius of a circle is half of the half of a circle. So, imagine having a line cut through a circle (the diameter). Half of that line is called the radius. In mathematical format, the diameter over two, or divided by two, is the radius.

Diameter is the radius times 2, you can visualize it as a straight line cutting a circle in half.

Now, knowing this information, if the radius is two inches, all you have to do is 2*2, which is 4.

In conclusion, the answer would be 4 inches, or 48 centimeters if you want to get specific.

Answer: v <= 1

Step-by-step explanation:

When you have a variable by a number, you do the opposite of multiplying, so you divide

Since there's only 14v you divide 14 from itself leaving just the variable

14 ÷ 14 = 1

You repeat this and divide on the other side

14 ÷ 14 = 1

Since you arent dividing by a negative on both sides, the arrow stays the same

v <= 1

Hope this helps!

Gregory’s age is 5 years greater than of Amanda’s age. Gregory is 17 years old. If Amanda’s age is denoted by x, which equation

Mariana [72]

Let Amanda's age = x.
Gregory's age = x + 5.

Since Gregory is 17 years old.
17 = x + 5
x = 17 - 5
x = 12

Amanda is 12 years old.

The human population of the earth can be modeled by p(T)=3.1(1.016)^t , where T represents the number of year since 1963 , and p

Mkey [24]

Answer:

See below

Step-by-step explanation:

Given function:

p(t)=3.1(1.016)^t

The base of the growth rate is:

1.016 = 1 + 0.016

It represent a 1.6% of growth per year.

Increasing

p(55) = 7.42 means:

55 years after 1963, in the year 2018, the population of Earth is 7.42 billions
